Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10308, here are decompositions:

5 + 10303 = 10308
7 + 10301 = 10308
19 + 10289 = 10308
37 + 10271 = 10308
41 + 10267 = 10308
61 + 10247 = 10308
97 + 10211 = 10308
127 + 10181 = 10308

Showing the first eight; more decompositions exist.
